Done some digging and this may be of interest. Peter Gyllenhammar is a director with Union Investment Management which cites on its website that among its activities is "Principle Investing on behalf of the Browallia Group".
Quoted from the site also:
"We select our investments by rigorous research looking for under-valued companies in the small cap arena. Typically these are companies that have fallen out of favour with the market and trade at significant discount to their net asset value.
We generally work with management to bring about change in one form or other. This process can be achieved through a consolidation process, disposal of surplus assets or disposal or redevelopment of property. Union Investment Management has a focused property team led by Chris Tomlin. This team has the skills to deliver inventive solutions to property investments."
